I feel like the jump from what the comment u were replying to was saying, I.E. something ‘easier’ might be harder in the long run to saying it’s sad scientists need to collect empirical evidence to prove things like fasting and ”extreme hot/cold” (I assume temperatures?) are good is a big one and not necessarily a good one.

What good would fasting or these extreme temps do and how would we prove it if not for evidence.

Scientists are NOT the problem here.
